Audio bug with metal Pokemon (Desktop)

I noticed an annoying bug with the desktop client.

I have music and sound effects turned all the way down in the sound options. Whenever my opponent plays a metal Pokemon the sound effect that goes along with the field animation will play.

Just really annoying since I have all sound turned down so I can play music in a another app.

Also when will we be able to see our card collection outside of building/editing a deck? It's been over a year since I and several others have complained about this glaring omission.
